Sleep debt is the cumulative difference between the amount of sleep your body needs to function optimally and the amount you actually get. It's a deficit that builds up over time due to consistent sleep deprivation.
Common symptoms include persistent fatigue, daytime sleepiness, difficulty concentrating, irritability, impaired memory, decreased performance, and an increased likelihood of microsleeps during the day.
Repaying sleep debt involves consistently getting more sleep than usual over several nights or weeks, often by extending bedtime or waking up later. Strategic naps can offer some temporary relief, but consistent longer nights are key.
Chronic sleep debt can increase the risk of serious health problems such as obesity, type 2 diabetes, cardiovascular disease, weakened immune function, high blood pressure, and mental health issues like anxiety and depression.
